| 摘 要： | 针对某高架结构地铁车站进行了火灾烟气数值模拟,根据模拟结果对不同楼梯间形式下,地铁站的烟气流动、温度场和能见度进行分析。最后,对该火灾场景下地铁站的人员安全问题(对照人员疏散模拟分析结果)进行了讨论,得到以下结论:以现有的排烟条件,发生在站厅层的火灾可能会造成人员伤亡。针对以上结论,本文提出如下建议:增加封闭楼梯间,并参照《建筑设计防火规范》有关楼梯间加压送风的规定,对该封闭楼梯间进行加压送风;增加站厅层机械排烟系统的排烟量。

| Abstract: | CFD numerical simulation is performed to investigate the fire smoke in an elevated structure metro station.Then,a brief analysis of the fire is given according to th Different forms of the staircase,which includes the flow directioin,the temperature and the visibility of the metro-station-fire-smoke.Finally,a discussion about the safety of the personnel working at a fire scene is made in comparison to the simulation analysis of the personnel evacuation in the same station.The comparison shows that the fire ... |
